We've Seen a Helicopter on Mars. Next, Sailplanes?

The success of the Mars Ingenuity helicopter has encouraged engineers to consider and reconsider all options for remote aerial observations of the Red Planet. Additional methods for birds-eye views of Mars would not only provide higher resolution data on the landscapes where rovers can’t go — such as canyons and volcanoes — but also could include studying atmospheric and climate processes that current orbiters and rovers aren’t outfitted to observe.

Despite its draining power, NASA’s InSight Mars lander is determined to squeeze as much science as it can until the very last moment

Its solar panels are caked with dust and the batteries are running out of juice, but NASA’s InSight Mars lander continues to soldier forth collecting more science about the Red Planet until its very last beep. To conserve energy, InSight was projected to shut down its seismometer—its last operational science instrument—by the end of June, hoping to survive on its remaining power until December. The seismometer has been the key instrument designed to measure marsquakes, which it has been recording since it touched down on Mars in 2018, and recently recorded a 5.0-magnitude quake, the biggest yet.

This Bizarre Terrain on Mars is Caused by Water Ice and Carbon Dioxide

From orbit, this landscape on Mars looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren’t created by Martian bees or spiders; they are actually formed from a ongoing process of seasonal change from created from water ice and carbon dioxide.

A Perfectly Balanced Rock Seen by Perseverance

NASA's Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover's mast. This image was acquired on June 12, 2022 (Sol 466) at the local mean solar time of 12:20:39. Image Credit: NASA/JPL-Caltech/ASU

The Perseverance rover has begun exploring a region that looks a little like Monument Valley in Arizona and Utah in the US, or perhaps like a set on an old sci-fi movie. The rover’s science team has nicknamed the area “Hogwallow Flats,” and the rock formations in this area on Mars are stunning in their varied and sometimes absurd shapes and structures. One wonders what took place here eons ago to create the weird variety of formations.

While small, one feature catches the eye: a smaller rock that appears to be perfectly perched and balanced on top of a larger rock formation.

Japan’s Upcoming Mission Will Use a Vacuum to Get its Sample From Phobos

JAXA, the Japanese Aerospace Exploration Agency, is carving out a niche for itself in sample-return missions. Their Hayabusa mission was the first mission to sample an asteroid when it brought dust from the asteroid Itokawa to Earth in 2010. Then its successor, Hayabusa 2, brought back a sample from asteroid Ryugu in 2020.

Now JAXA has the Martian moon Phobos in its sights and will send a spacecraft to sample it as soon as 2024. The mission is called Martian Moons eXploration (MMX), and it’ll use a pneumatic vacuum device to collect its samples.

Will Earth’s Follies Take Root on Mars? Black Comedy Explores the Frontier

The world’s richest human wants to build a city on Mars: Fifty years ago, Elon Musk’s vision of our future on the Red Planet might have sounded like science fiction — but today, Musk is actually serious about the idea of using billions of dollars from ventures like SpaceX’s Starlink broadband network to finance the move to Mars.

“In looking in the long term, and saying what’s needed to create a city on Mars, well, one thing’s for sure: a lot of money,” Musk said back in 2015. “So we need things that will generate a lot of money.”

What kind of city would Musk want to see on Mars? His vision calls for a place that offers “everything from iron foundries to pizza joints to nightclubs” while getting rid of “special interests and coercion of politicians.” But what if cities on Mars turn out to be like cities on Earth, complete with wealth disparity, racism — and ambitious billionaires?

That’s the premise for “Maurice on Mars,” a darkly funny series of animated shorts created and written by comedian and TV writer Tim Barnes for Comedy Central’s Animated YouTube channel.

Perseverance Has Been Carrying a Rock in its Wheel for Over 100 Days

NASA's Mars Perseverance rover acquired this image of a rock inside the rover's wheel, along with the area in front of it using its onboard Front Left Hazard Avoidance Camera A. This image was acquired on May 26, 2022 (Sol 449). Image Credit: NASA/JPL-Caltech

Why does a Mars rover have a rock in one of its wheels? Maybe it’s because a rover doesn’t have pockets.

Who among us hasn’t picked up a great rock, carried it around, maybe saved it for a long time, or even placed it somewhere safe or special? The Perseverance rover is doing just that, having carried a random Mars rock in its wheel for quite some time.

This is the Last Selfie InSight Will Ever Take

Few things in life captivate us more than looking at images from other planets, no matter how dull these images might seem. This is especially true for Mars, as it’s where we’ve sent the most robots to explore its cold and dry surface. The very first image from the surface of Mars in July 1976 was nothing more than the Viking 1 lander’s footpad and some rocks, but no one cared about these mundane details because we were looking at an image from Mars. We were looking at the surface of another world for the first time in human history, and not only were we captivated by it, but we wanted more.

Perseverance is Seeing A LOT of Dust Devils

While the Mars InSight lander is still waiting for a passing dust devil to clean off its solar panels, it appears the Perseverance rover sees dust devils several times a day.

A new paper detailing the first 216 days of Perseverance’s mission in Jezero Crater reports how the newest rover on Mars appears to be located in a “dust storm track” that runs north to south across the planet. Jezero Crater has particularly high levels of dust and wind activity.

The “Doorway on Mars” is More Like a Dog Door

Remember all the fuss about the “doorway on Mars” from just last week? Well, this week, NASA issued some more information about the rock mound where the Curiosity rover snapped a pic showing a fracture hole in the rock. It looks like a door, but it’s not.
